Ground roll wave has characteristics of strong energy , low frequency and slow attenuation 摘要面波具有能量强、频率低、吸收衰减缓慢等特点。
By using band and equal distance wavelet transform and average energy method , the ground roll wave can be recognized and suppressed belier , hence obtaining good results 采用窄档等频距小波变换方法,在含面波的低频频带内,用平均能量法识别和压制面波,取得良好效果。
Company profile : it is a newly built italian enterprise that works on researching , processing , manufacturing and selling for ground belt 、 ground roll 、 ground wheel and other ground products 公司是研发加工、制造、销售研磨带、研磨卷、研磨轮等研磨制品的新建意大利独资企业。
In the low band of wavelet transform , energy of ground roll wave is normally greater than the average energy in overall band of seismic reflection event , which is regarded as the discrimination criterion for it 在小波分频后的含面波频带内,同一时刻较强面波能量总要比该时刻全排列的平均能量大得多,这是分频识别强面波的判别准则。
